The U.S. U-16 and U-17 girls national teams are capping off their 2007 seasons with trips to South America. The U-17s are in Buenos Aires until next Monday, while the U-16s are in Rio de Janeiro until Sunday.

U.S. U-17 coach Dean Duerst invited in 18 players, all but one born in 1990, for the trip to Argentina. A combined Argentine U-20/U-17 national team beat the U-17s, 2-1, in their first game on Monday. The U-17s face Arggentina's U-17s on Wednesday and Uruguay's U-17s on Saturday.

U.S. U-16 head coach Kazbek Tambi brought in 18 players, born in 1991 and 1992, as they continue preparation for qualifying for the inaugural U-17 Women's World Cup, to be played next fall in New Zealand in 2008.
